Songwriter J.J. Cale, famous for the Eric Clapton hits "Cocaine" and "After Midnight," died Friday night after suffering a heart attack at Scripps Hospital in La Jolla, Calif., according to the musician's website.

"J.J. Cale was loved by fans worldwide for his completely unpretentious and beautiful music," Mike Kappus, president of the Rosebud Agency, told CNN. "He was loved even more dearly by all those he came in contact with as the most real and down-to-earth person we all knew."

Kappus continued, "He was incredibly humble and avoided the spotlight at all costs but will be missed by anyone touched by him directly or indirectly. Luckily, his music lives on."

Along with Clapton's famous singles, Cale was the mastermind behind Lynyrd Skynyrd's "Call Me The Breeze," along with a number of tracks from Santana, The Allman Brothers and Johnny Cash.

He won a Grammy for his 2006 album with Clapton, called The Road to Escondido.

"I remember when I made my first album [1972's Naturally], I was 32 or 33-years-old and I thought I was way too old then," Cale said, according to his bio. "When I see myself doing this at 70, I go, ‘What am I doing, I should be layin' down in a hammock.'"
